Intelligent crane control For functional and safe crane operation: the LICCON computer system The soft and hardware of the mobile crane control is developed by Liebherr inhouse. The centre is the LICCON computer system (Liebherr Computed Control). • Integrated LML load moment limiter • Key components are in-house manufactured by Liebherr • Guaranteed spare parts availability • Worldwide proven under the most different climate conditions • Operator friendly The second control generation LICCON2 is the result of a continuous development by the Liebherr specialists and enables the adaption to the constantly increasing demands of the markets due to its modern and future oriented control.
The data bus technology Liebherr mobile cranes are completely interlaced by the data bus system. All important electric and electronic components are equipped with own micro processors and communicate with each other by only limited data cables. For the special demands of the mobile crane Liebherr has developed own data bus systems (LSB – Liebherr-System-Bus). The data bus technology improves the reliability, the comfort and the safety for road driving and crane operation: • Higher reliability due to remarkable lesser electric cables and contacts • Continuous self testing of the „intelligent sensors“ • Comprehensive diagnosis possibilities, fast fault finding
The LICCON working area limiter (option)
The LICCON work planner
• Relief of the crane driver by automatic monitoring of working area limits like bridges, roofs, etc.
• Computer programme for planning, simulating and documenting crane operations on a PC
• Simple programming
• Representation of all the crane’s load charts
• Four different limiting functions: - Sheave head height limiting - Limiting of radius - Limiting of slewing angle - Limiting of borders
• Automatic search for suitable crane based on entry of load, radius and lifting height parameters • Simulation of crane operations with outline functions and supporting force display
The readability of the data on the monitor of the LICCON2 control unit in the crane cabin is improved by the colour display. Warning indications and crane utilisation are more clearly visible.
Below the joysticks integrated in the arm rest touch displays are provided with which various working functions can be selected. Beside others these are the drive and steering programmes of the carrier, the axle suspension, the supporting of the crane, the adjustment of the working floodlights as well as the heating and ventilation control.
LICCON2 – safe and comfortable Attaching and detaching the hook block The BTT – Bluetooth terminal allows the crane driver to attach the hook block or detach it from the front bumper within view by remote control of the hoist gear and the luffing cylinder of the telescopic boom.
Crane supporting By use of the BTT the mobile crane will be set up comfortably and safely. Engine start/stop and speed regulation, electronic inclination display and automatic levelling are standard. Optionally the BTT can also display the outrigger forces.
Wireless remote control (option) All crane movements can be controlled outside the crane cab. By this system the economy of crane operations is enhanced. • Free visibility and closeness to the load • Prevention of communication errors between crane driver and job side personnel • Independent attaching of the load by the crane driver
